摘　　要：为降低地下水源地供水能耗,提高供水安全保障,以地下水源地供水单位耗电量最低为目标函数,以井泵运行时长为约束条件,采用节点水压法建立地下水源地任意组合的水力计算模型,确定最优的供水调度方案与井泵运行频率,使整个系统运行功耗最低,实现供水的安全运行。此模型已在L市地下水源地应用,改变了传统的水源地井泵长时间以恒频运行的状况,并增加了水源井轮换运行的功能,实现了地下水源地的智能化优化运行。实际运行表明,L市地下水源地应用水力计算模型后,单位耗电量明显下降,每日节省耗电量,节能约38%,供水水质稳定,保障了供水安全,提高了系统的智能化水平。In order to reduce the energy consumption of water supply in underground water source and improve the safety of water supply,taking the lowest power consumption per unit of water supply in underground water source as the objective function and the operation time of well pump as the constraint condition,the node-pressure method was adopted to establish a hydraulic calculation model of any combination of underground water source and determine the optimal water supply dispatching scheme and the operation frequency of well pump,so as to minimize the power consumption of the entire system.Achieve safe operation of water supply.This model has been applied to the underground water source in L city,which changes the situation of the traditional water source well pump running at constant frequency for a long time,and increases the function of the water source well rotating operation,realizing the intelligent and optimized operation of the underground water source.The actual operation shows that after the application of hydraulic calculation model in L City underground water source,the unit power consumption is significantly reduced,the daily power consumption is saved,the energy saving is about 38%,the water supply quality is stable,the water supply safety is guaranteed,and the intelligent level of the system is improved.
